Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2008.<br>Includes bibliographical references (p. 62).<br>Design of switched capacitor circuits in scaled CMOS technologies is becoming difficult because of low device intrinsic gain and reduced power supply voltage. To solve these problems, comparator-based switched-capacitor (CBSC) circuits and zero-crossing based circuits (ZCBC) were suggested as a possible solution to the op-amp based circuits. In this thesis, we explore zero-crossing based circuits (ZCBC) in high-order differential s

Abstract:

CDMA channel selection requires sharp as well as wide-band Filtering. SAW Filters which have been used for this purpose are only available in IF range. In direct conversion receivers this has to be done at low frequencies. Switched Capacitor technique has been employed to design a low power, highly selective low-pass channel select Filter for CDMA wireless receivers. The topology which has been chosen ensures the low sensitivity of the Filter response. The circuit has been designed in a mixed-mode 0. 18u CMOS technology working with a single supply of 1. 8 V while its current co

Abstract:

Phase locked loops (PLL) are used in a variety of RF integrated applications because of their ability to generate precise clock signals. These applications include clock recovery systems, frequency synthesizers and frequency multipliers. In order to achieve small size and low cost targets, the PLLs must be fully integrated on-chip with all the necessary components. Unfortunately, the filtering requirement for the low pass filter (LPF) demands a large silicon area, or the use of external capacitors. Moreover, high-density recording and high data rates for image transfer systems in wireless comm

Abstract:

Analog-to-Digital Converters (ADCs) can be classified into two categories namely Nyquist-rate ADCs and OversampledADCs. Nyquist-rate ADCs can process very high bandwidths while Oversampling ADCs provide high resolution using coarse quantizers and support lower input signal bandwidths. This work describes a Reconfigurable ADC (R-ADC) architecture which models 14 different ADCs utilizing four four-bit flash ADCs and four Reconfigurable Blocks (RBs). Both Nyquist-rate and Oversampled ADCs are included in the reconfiguration scheme. The R-ADC supports first- and second-order Sigma-Delta (ΣΔ) ADCs.

Two software programs have been developed to automatically generate the layout of stray insensitive switched capacitor filters. The first program, CIRCE, uses a SWITCAP filter description to generate an intermediate format filter description that is suitable for direct layout. It groups the filter elements into integrators and then sorts these integrators and their elements. The SWITCAP description can be with or without switch-sharing. The second program, SISCL, lays out the filter in CIF format using a double-polysilicon ISOCMOS process. The layout is done with a capacitor array placed over

This thesis investigates the various techniques to achieve large time constants and the ultimate limitations therein. A novel circuit technique for the realization of large time constants for high pass corners in switched-capacitor filters is also proposed and compared with existing techniques. The switched-capacitor technique is insensitive to parasitic capacitances and is area efficient and it requires only two clock phases. The circuit is used to build a typical switched-capacitor front end with a gain of 10. The low pass corner is fixed at 200 Hz. The high pass corner is varied from 0.159H

Abstract:

碩士<br>國立交通大學<br>電機與控制工程系所<br>92<br>As IC fabrication technology advances in recent years, faster and more complex test equipments are required to achieve test specifications and test functions. An innovative method to simplify the test equipment is to move test functions onto the chip itself, which is called Built-In-Self-Test (BIST). How to achieve on-chip test function with limited area and power overhead is the main issue for mixed-signal testing designers. In this thesis, we accomplish a fully-differential, 140 MHz sampling frequency, 10 MHz corner frequency, switched-capacitor 4th-ord
